摘要
使用一维棒状ZnTiO_3粉体光催化降解罗丹明B溶液,采用正交试验研究罗丹明B溶液pH值、溶液初始质量浓度、ZnTiO_3用量和紫外光照时间四个因素对降解效率的影响规律.结果表明,在pH值为10,罗丹明B溶液初始质量浓度为5 mg/L,ZnTiO_3用量为250 mg/L,光照反应90 min后,罗丹明B溶液的脱色率达98.5%.
The photocatalytic activity of one-dimensional ZnTiO_3 rods was investigated by the degradation reaction of Rhodamine B. The effects of the p H value,initial concentration of Rhodamine B solution,irradiation time and ZnTiO_3 dosage on degradation rate were optimized by orthogonal design. The results indicated that degradation rate of Rhodamine B was up to 98. 5% at the p H value 10,initial concentration 5 mg/L,catalyst dosage 250 mg/L and irradiation time 180 min.
